Jury: Apple infringed on Wisconsin university's tech patent

MADISON, Wis. (AP) — A federal jury that found Apple Inc. infringed on a technology patent held by the foundation that protects the University of Wisconsin's intellectual property has begun hearing testimony in the damages phase of the case.

The jury in Madison on Tuesday rejected claims from the technology giant that the patent was invalid and no infringement took place. On Wednesday, both sides presented testimony on damages in a phase expected to last into Friday.

The Wisconsin Alumni Research Foundation sued Apple in 2014 claiming it used the foundation's patented technology in its latest processors, which power iPhone and iPad devices.

The technology dates to 1998 when the work of four UW researchers was patented. The foundation sued Intel Corp. over the same patent in 2008 and settled for an undisclosed amount.
